WELL-DRILLING MACHINE.

To all whom it may concern Be it known that I, FREDERICK A. HEBER- LING,a citizen of the United States, residing at Centralia, in the county ofMarion and State of Illinois, have invented certain new and usefulImprovements in Vell- Drilling Machines; and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to improvements in well drilling machines.

One object of the invention is to provide a well drilling machine havingan improved construction and arrangement of spudding mechanism.

Another object is to provide an improved construction and arrangement ofdriving mechanism for the winding drum of the tool operating cable andmeans whereby said driving mechanism is quickly thrown into and out ofgear.

With these and other objects in view, the invention consists of certainnovel features of construction, and the combination and arrangement ofparts as will be more fully described and particularly pointed out inthe claims.

In the accompanying drawings: Figure 1 is a side view of a well drillingmachine showing the application of my invention; Fig. 2 is a top planview thereof; Fig. 3 is a vertical longitudinal section showing theconstruction and arrangement of the spudding mechanism; Fig. '-1 is adetail sectional view of the spudding cam and means whereby the spuddingcable is connected thereto; Fig. 5 is a side view of the parts shown inFig. 4; Fig. 6 is a detail sectional view through one side of the frameon the line 6-6 of Fig. 1 showing the manner in which the slidingbearing box of the tool operating shaft is secured to the frame of themachine.

Referring more particularly to the drawings, 1 denotes the frame or bodyof the machine which is provided at its rear end withsupporting wheels 2and at its front end with supporting and steering wheels 3. Arranged onthe frame or body 1 preferably at the rear end and adjacent toone sidethereof is a horizontal engine 4. On the crank shaft of the engine ismounted a drive pulley 5 which is connected by a Specification ofLetters Patent.

main drive belt 6 to a large main drive pulley 7 fixed on the outer endof a drive shaft 8 journaled in suitable hearings on the frame near itsforward end as shown. On the opposite end of the drive shaft 8 from thewheel 7 is fixedly mounted a crank arm 9 having arranged therein anadjustable crank pin 10 which is pivotally connected the lower end of apitman rod 11 the upper end of which is connected with one end of awalking beam 12 which is pivotally mounted on suitable supporting bars13 arranged on and projecting upwardly from the frame adjacent to oneside of the same as shown. To the outer or free end of the walking beamis secured the usual or any suitable cable engaging mechanism 14 wherebythe tool operating cable may be readily connected wit-h and disconnectedfrom the walking beam.

Arranged at a suitable position on the frame of the machine is a cablewinding drum 15 on which is adapted to be wound a tool operating cable16. The shaft 17 of the drum 15 is loosely mounted at one end in abearing 18 secured to one side of the frame and at its opposite end isloosely mounted in a bearing 19 which is slidably secured to theopposite side of the machine by clips 20 which are bolted to theadjacent side beam of the frame and have their upper portions projectinga slight distance above said beams to form guide loops with which areengaged oppositely projecting lugs 21 formed on the lower portion of thebearing 19 whereby the latter may be shifted on the side beam of theframe. On the shaft 17 of the drum 15 is fixedly mounted a frictiondrive gear 22. The gear 22 is preferably provided with a V-shapedperiphery which when the shaft 17 is shifted in the proper direction isadapted to be brought into frictional engagement with the similarlyshaped periphery of a friction drive gear 23 fixed on the main driveshaft 8 whereby the motion of said shaft is imparted to the shaft 17 andthe latter and the winding drum 1;) thus driven in the proper direction.The bearing 19 of the shaft 17 is shifted to bring the gear 22 on saidshaft into engagement with the gear 23 on the drive shaft by means of ashifting mechanism comprising a shifting lever 24L which is connected bya link 25 to a lug 26 on the adjacent bearing of the drive shaft 8 ontosome other fixed point. The lever 24 is also connected at its lowerendor below the link to the bearing 19 of the shaft 17 bymeans of a link 27whereby when sald lever is swung in one direction or the other thebearing 19 and the shaft 17 W1ll be shifted to bring the friction gear22 mto and out of operative engagement with the friction gear 23 on themain drive shaft thus providing for .the operation of the drum 15 forwinding the cable 16 or permitting the same to unwind therefrom. Thelever 24 is preferably connected by an operating rod 28 to a hand lever29 arranged on the rear end of the frame within convenient reach of theoperator, said hand lever being provided with a suitable pawl andratchet locking mechanism whereby said lever 24 and the parts shiftedthereby are fastened in their adjusted positions.

Fixedly mounted on the main drive shaft 8 is a spudding cam 30comprising a disk having on its outer edge laterally extendlng annularflanges 31 with which are adapted to be engaged bearing rollers 32arranged on the ends of a grappling hook coupling member 33 the handleends of which are in the form of overlapping hooks 34 which are adaptedto hook into an eye or link 35 secured to one end of a spudding cable 36the opposite end of which is adapted to be con nected with the tooloperating cable 16 by means of the usual or any suitable form of slidingconnection 37. By constructing the grappling hook coupling 33 as hereinshown and described it will be seen that when the hook shaped handles 34of the coupling are engaged with the eye or link 35 that the rollers 32on the opposite ends or jaws of the coupling will be held in operativeengagement with the flanges 31 of the spudding cam. By thus constructingand arranging the spudding mechanism the latter may be readilydisconnected from the spudding cam and the tool operating cable whensaid cable is to be operated by the walking beam.

Revolubly mounted in suitable bearings in theforward end of the machineis a sand line shaft 38 on which is fixedly mounted the winding drum 39of the sand bucket operating cable 40. On the end of the shaft 38adjacent to the main drive pulley 7 is fixed a friction drive pulley 41which is operatively engaged with the inner surface of the rim at theperiphery of the main drive pulley 7 whereby said shaft 38 is driven inthe proper direction for winding the cable 40. The end of the shaft 38on which the pulley 41 is fixed is mounted in an eccentric sleeve 43arranged in the adjacent bearing of the shaft and provided with a lever44 whereby the same may be turned to shift this end of the shaft andthereby.

swing the friction pulley 41 into and out of engagement with the innersurface of the rim of the drive pulley 7 thereby throwing the shaft 38into and out of operation.

Journaled in suitable bearings near the rear end of the machine is acasing line shaft 45 011 which is fixedly mounted a casing line reel orwinding drum 46 on which is adapted to be wound the casing driving cable47. On one end of the shaft 45 is loosely mounted a sprocket gear 48which is connected by a sprocket chain 49 with a sprocket gear 50 fixedon the main drive shaft 8 as shown. The sprocket gear 48 is providedwith one member of a clutch 51 the opposing member 52 of which isslidably keyed to the shaft 45 and is adapted to be thrown into and outof engagement with the clutch member of the gear 48 by means of ashifting lever 53 whereby said sprocket gear is locked to and releasedfrom the shaft 45 and the latter thus driven.

The tool operating cable 16, the sand bucket operating cable 40 and thecasing driving cable 47 are each extended upwardly and are respectivelyengaged with guide pulleys 54, 55 and 56 which are revolubly mounted inthe upper end of the usual mast or derrick 57 arranged at the rear endof the machine and from said pulleys said cables extend downwardly andare connected with their respective operating devices.

On one end of the shafts 17 and 45 are mounted friction band pulleys 58with which are engaged friction bands 59 one end of each of which issuitably fixed and the other end connected with an operating lever 60whereby said bands may be drawn into frictionalengagement with thepulleys thereby stopping or retarding the movement of the shafts and thedrums operated thereby.

By constructing and arranging the various parts of the machine inaccordance with myinvention it will be seen that separate cables areprovided for the spudding and drilling operation, the sand balingoperation and the casing driving operation and that each of said cablesis provided with a separate and independent operating mechanism havingmeans for controlling or throwing the same into and out of operation.

Particular attention is invited to my improved means for actuating thedrilling or tool operating cable during the spudding operation wherein asteady pull and quick release of the cable are provided for and whichmay be readily disconnected from the cable when the spudding operationis completed. Attention is also called to the improved arrangement ofthe various parts of the machine whereby space is provided adjacent toone side and near the rear end of the machine for a horizontal engine.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention claimed.
